Durkheim analyzed suicide rates using official statistics to show that suicide is influenced by social forces rather than individual factors. He identified four types of suicide based on levels of social integration and moral regulation: egoistic suicide results from low integration; altruistic from over-integration; anomic from deregulation; and fatalistic from over-regulation. Durkheim's study was groundbreaking in establishing sociology as a science and demonstrating that social patterns can explain phenomena previously viewed as individual issues like suicide. However, later positivists criticized Durkheim for not fully operationalizing his concepts and for overemphasizing some social factors over others.
